So my inlaws have a 2001 Audi S8 with approx 100k miles. Being members of AARP, this was, and still is, the wrong car for them - they're into the luxury not the performance. My mother in law is thinking of selling or trading in. How should we find the value and list it for sale - an Audi enthusiast forum?
I don't think they're ready to move on it tomorrow, but they did just drop a bundle on misc repairs at the dealer and its stirring up thoughts of "why do we still own this?"
Thank you for your wisdom.
